Design and Research of Light Space Polarization Camera Based on Hyperlens Integration Technology

Abstract

Polarization optical imaging technology is a new earth observation method based on the detection of the polarization information of the reflected light of the target. Compared with the traditional intensity imaging technology, it is of great significance in improving the ability of target detection. Hyperlens is a planar optical device whose metasurface has great application potential in the field of imaging. It has promising development prospects in the light weight and mass manufacturing of devices. Combining the advantages of the two, from the perspective of small, simple and easy integration design of optical multi-dimensional information acquisition device, the integration of traditional hyperlens array and image sensor has monolithic integration and hybrid integration. According to the practical application requirements, the implementation of structural integration is studied, and system scheme of high spatial resolution polarization imaging is proposed, and the engineering of the system is realized. In order to verify the rationality of the scheme, an engineering prototype of the polarization camera is designed and developed. The location imaging experiment of the camera is carried out, and the results are consistent with the expectation. The development process of the engineering prototype is summarized, and the problems that need to be considered are put forward, which lays a foundation for the subsequent application of polarization camera in the model.
